 ## Missing browser command or tool
 
 If `openclaw browser` is unknown after an upgrade, `browser.request` is missing, or the agent reports the browser tool as unavailable, the usual cause is a `plugins.allow` list that omits `browser` and no root `browser` config block exists. Add it:

+   - For “read the page and answer X,” use `action="extract"` with `query` so only the answer returns.
+   - Use `action="snapshot"` instead when you need action refs or page structure.
+   - If extract returns `NOT_FOUND` or asks for snapshot fallback, inspect the page with a snapshot.
    - Use `action="snapshot"` on the intended `targetId`.
    - Use the same `targetId` for follow-up actions so refs stay on the same tab.
    - For durable Playwright refs, request `refs="aria"` when supported. If you receive `axN` refs from `snapshotFormat="aria"`, use them only after that same snapshot call; stale or unbound `axN` refs fail fast and need a fresh snapshot.
